IMPROVEMENT IN WElGHlNG-SCALES.

Specification forming part of Letters Patent No. 116,999, dated July 11, 1871.

To all whom it may concern:

Be it known that I, GEORGE SCOTT, or the city of Montreal, in the district of Montreal, in the Province of Quebec, Canada, machinist, have invented a new and useful Improved Combina tion Scale, and I do hereby declare that the tollowing is a full, clear, and exact description oi' the construction and operation ot' the same, reference bein g had to the annexed drawing, where- Figure I represents an elevation of the scale. Fig. II represents a section of the scale on line A B, Fig. I.

This invention relates to that class oi' scales which is provided-with a twine-box and weightplate, and consists in certain details ot' construction, which will be fully described hereinaiter.

To enable others skilled in the art to make and use my invention, I will now proceed to describe fully its construction and manner of operation.

a c represent the standards of an ordinary pair of scales, which are united in the center by the stretcher c, which is constructed with a semispherical receptacle, d, as shown in Figs. I and II. Rising from the receptacle on each side are standards for supporting the center bar of the balance-bean'i b, which is provided with a central (-.ircular opening, through which projects the weight-plate j' attached to the semi-spherical cover c, as shown. The upper edge ot the receptacle. dy is provided with a series o1' semicireular notches or openings, through anyone ot' which the twine may be drawn.

It will be observed that the twine-box and the plate/'for holding the weights are connected to the sea-le without increasing its size or inter-tering with its workings.

H avin g thus fully described my invention, wh at I claim as new, and desire to secure by Letters Patent, is-

The semi-spherical twine-receptacle d, provided with suitable openings for the withdrawal of the twine, in combination with the semi-spherical cover c with plate j", the latter being adz'tpted to hold the weights and serve also as a handle ii'or raising the cover, the holder d c being located beneath the lni-lancefbeam, so that the twine may be withdrawn therefrom without inter ii'erin g with the movements of the scale, as described.

Montreal, 22d Oct-ober, 1870.

GEORGE SCOTT.
